Nitrogen Deficiency?

Hello, Nitrogen deficiencies usually affect the older leaves at the bottom of the plant. This seems like the whole plant is affected. The low PH last week might play a role in her appearance but my attention is turned towards the leaves that are blistering and deformed. If those leaves look wet even when you haven’t sprayed them I would suspect they are getting eaten by mites. Most likely broad mites. Have a real good look under her leaves with magnification if possible to rule out the possibility. Fingers crossed 🤞 Cheers 🍻
